Microtubules are a basic of the cytoskeleton. These rope-like polymers of tubulin can abound as continued as 25 micrometers and are awful dynamic. The central of the microtubule, alleged the lumen, is 25 nm in diameter. Microtubules are important for advancement corpuscle structure, accouterment platforms for intracellular transport, basic the arbor during mitosis, as able-bodied as added cellular processes.[2] There are abounding proteins that bind to the microtubule, including motor proteins such as kinesin and dynein, disengagement proteins like katanin, and added proteins important for acclimation microtubule dynamics.
